SHEARS.

SPECIFICATION forming part Of Letters Patent NO. 628,483, dated July 11,1899. Application filed August 19, 1897- Serial No. 648,765. (No model.)

To all whom it may concern-.-

Be it known that I, FRANK MAORI, of the town of Huntington, in thecounty of Baker and State of Oregon, have invented an Improvement inShears; and I declare the following to be a full, clear, and exactdescription thereof.

My invention relates to shears which are constructed of two parts, eachpart including one of the blades.

It consists in providinga peculiar joint by which either of the partsmay be joined to or detached from the other without the use of screws,bolts, or other equivalent devices. The advantage gained is that the twoblades can readily be detached for the purpose of sharpening or makingrepairs and can as readily be joined together for use.

In the accompanying drawings, Figure'l represents a plan of the shears;Fig. 2, an elevation; Fig. 3, an elevation showing, on a larger scale,the jointby means or which the two parts of the shears are detached andjoined. It also indicates the manner in which this joint is operated.Figs. 4 and 5 are isometric projections of theparts of the shears whendetached.

Throughout the drawings the same letter is used to indicate the samepart of the device.

A represents a sprin g-bow. which is provided with shanks or handles band c.

B represents one of the blades of the shears, which is permanentlyjoined to the springbow by the shank or handle b.

The shank or handle 0 at its end farthermost from the spring-bow A isfitted with the lip E, which extends inward, forming a perpendiculargroove 9 of suitable size to accommodate the shank 7c of the blade 0.The shank or handle b, the spring-bow A, and the shank or handle 0, withits lip E, preferably should be made of one piece of, metal, but may bemade of two or more parts welded or otherwise permanently joinedtogether. The blade 0 is fitted with'the shank 7.3, which at itsextremity farthest from the blade C is fitted with a curved lip F,extending outward from the blade when in position as part of the shears.the shank k, a perpendicular groove h, which is made of suitable size'tofit the shank or handle 0. r

The two parts may be fitted together as follows: by placing the shank 7clongitudinally 7 against the shank or handle 0, so that the lip F shallengage the shank or handle 0, which will then pass into the groove h,and the lip E shall engage the shank 7a, which will then pass into thegroove 9' in the manner shown by Fig. 3. A joint is thus formed aboutwhich the two parts of the shears turn in a plane perpendicular to thoseof the blades. Either portion may then be turned until the shanks k anda come into proper alinement, as in Fig. 2. The lips E and F then comein contact with each other and prevent the shanks 7c and c from slidinglengthwise one upon the other. The blades B and C are made of such widthas to overlap when joined together for use, as indicated by Fig. 1. Theblade 0 is curved slightly upward from a point near that of its juncturewith the shank k. The result of this is that when the shanks b and 0have been brought in proper alinement the blade 0 is not in the sameplane as the blade B. The two blades are then pressed outward and whenfree from contact are pressed perpendicularly past one another againstthe spring of the metal of which they are composed until they engageupon their opposite faces, as shown by Fig. 2. When thus engaged, thejoint cannot rotate, and the blades are held firmly in a proper positionfor, use. The two blades can be detached with equal readiness by acourse the reverse of that by which they are attached.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

In a pair of shears composed of two distinct parts, the combinationofthe part consisting of the spring-bow A, provided with the handle orshank b, the blade B, the handle or shank c, the lip E, forming with theshank c the groove 9; with the part consisting of the blade 0, providedwith the shank It, the lip F, forming with the shank 7c the groove h;which two said parts may be joined together and detached from oneanother by means of the joint produced by adjusting the shanks 0 and 7c,the grooves g and h, the lips E and F and the blades B and C,substantially as described. The lip F forms, with the side of V Inwitness whereof I have hereunto set my hand.

FRANK MAORI.
